Transient analysis on different types of super conducting fault current limiters

This paper investigates the effect of installing series fault current limiters (FCL) on angular stability, voltage stability, as well as fault current mitigation. A resistive type (R-Type) HTS-FCL, and a magnetic HTS-FCL (MFCL) are modeled in time domain using PSCAD/EMTDC and tested in a single machine to infinite bus test system. To evaluate the performance of these FCLs they are compared with conventional series current limiting reactor SCLR. Machine´s internal voltage, rotor speed, and current are monitored for all cases. Simulation results demonstrate the effectiveness of HTS-FCL among other FCLs in boosting stator voltage and improving angular stability.
